[Feature Request] Provide a simpler method to run an app locally

[sk-]

Right now, there are several examples that run an app locally in sightly different ways (see tests/autobahn/server.py, examples/web_srv.py, examples/web_ws.py, http://aiohttp.readthedocs.org/en/stable/#getting-started and http://aiohttp.readthedocs.org/en/stable/web.html#run-a-simple-web-server). And if you want to start testing your app, you need to copy that (boilerplate) code snippet.

I propose adding a utility function, or a method to run and app locally in a simpler way.

Right now my utility function is as follows:

def run_app(app, host='0.0.0.0', port=8080):
    """Run an app locally."""
    loop = asyncio.get_event_loop()
    handler = app.make_handler()
    f = loop.create_server(handler, host, port)
    srv = loop.run_until_complete(f)

    if host == '0.0.0.0':
        host = '127.0.0.1'
    print(' * Running on http://{host}:{port}/ (Press CTRL+C to quit)'.format(
        host=host, port=port))

    try:
        loop.run_forever()
    except KeyboardInterrupt:
        pass
    finally:
        loop.run_until_complete(handler.finish_connections(1.0))
        srv.close()
        loop.run_until_complete(srv.wait_closed())
        loop.run_until_complete(app.finish())
    loop.close()

alternatively, this function could be a method of an app.

+1 for util function, also aiohttp package can define console script

What console script should do?

[fafhrd91]

something like aiohttp_srv -h 0.0.0.0 -p 8080 my_project.main

[jashandeep-sohi]

+1 for CLI, but is it a good idea to make aiohttp.web itself runnable?
python -m aiohttp.web HOST PORT pkg.module.main [ARGS]

[fafhrd91]

+1 for aiohttp.web
